When to use it
Use UltraFusion technology when a standard single-die chip architecture cannot handle the computational demands of intensive tasks. UltraFusion enables a quad-die architecture, allowing for enhanced processing power and efficiency for things like AI model training and complex simulations.
Quick example
In Apple's M5 Ultra chip, UltraFusion technology connects four chip dies to function as a single, cohesive unit. This technology is integral to the M5 Ultra, enabling it to perform high-demand tasks such as real-time 3D rendering and large-scale data analysis. The M5 Ultra chip itself is an example of UltraFusion in action, as it leverages this technology to achieve its advanced computing capabilities.
